Definitions
- the invention relates to a method for triggering a safety device in a motor vehicle in the event of a rollover process, in which the rotation rate signals generated by a rotation rate sensor are evaluated to detect a rollover of the motor vehicle around one of its axes.
- Roll-over bars, side airbags and belt tensioners are primarily considered as safety devices.
- a rollover of a motor vehicle For. With regard to its longitudinal axis (x-axis), for example, it is known to evaluate the rotation rate signals generated by a rotation rate sensor (gyro sensor).
- a corresponding evaluation method is known, for example, from DE 100 25 259 A1, in which a theoretical rollover characteristic curve in the form of an ⁇ - ⁇ graph adapted to the respective vehicle is assumed. This ⁇ - -G.raph is approximated by low-pass filter functions with certain cut-off frequencies and trigger thresholds that are respectively adapted to the rollover scenarios to be detected.
- the methods described in DE 196 09 717 A1 and DE 197 44 083 A1 derive the corresponding gimbal angles from the rotation rates measured in all three axes of a vehicle by integration in order to determine the position of a vehicle center of gravity projected into a horizontal plane and a rollover of the Signal the vehicle when the projected center of gravity exceeds the limits of a vehicle-fixed surface also projected into the horizontal plane.
- the rotational energy of the vehicle is derived from the rotation rates in order to detect a rollover when the rotational energy exceeds a certain threshold, which can be, for example, the potential energy required to drive the vehicle out tilt its current position into a position in which the center of gravity reaches its maximum distance from the road level.
- the object of the invention is to provide a method for triggering a safety device that requires little data material to be implemented and with which rollovers can be recognized in good time and reliably.
- the rotation rate signals generated by a rotation rate sensor with respect to an axis of rotation are both low-pass filtered with the aid of a low-pass filter with a cut-off frequency at which the signal components of the rotation rate signal that are characteristic of a rollover process pass unfiltered, and also to generate an integral value dependent on the rotation rate of the vehicle, whereby then a trigger signal for triggering a safety device is generated when the low-pass filtered rotation rate signal exceeds an adjustable trigger threshold value which is generated as a function of the integral value.
- the cut-off frequency of the low-pass filter used is preferably selected in such a way that rapid rollovers are recognized in good time and reliably.
- the cut-off frequency is a few Hz.
- the value of the triggering threshold value is determined by adjusted stability parameter of the vehicle displayed this parameter. If, for example, the transverse acceleration is used as a parameter, the triggering should take place earlier with a high acceleration value than with a low transverse acceleration of the vehicle, which with regard to the rollover Characteristic curve means a shift in the characteristic curve separating the no-fire area from the 'fire area. The method is thus more sensitive to lateral acceleration. If, however, the vertical acceleration of the vehicle are used as parameters, as' the flashover characteristic should also be shifted towards smaller values, when the acceleration value deviates significantly from the value of 1 g, that is indicative of a condition which is towards weightlessness.
- a further advantageous embodiment of the invention is to provide a further low-pass filter for filtering the rotation rate signal, the cut-off frequency of which is set in such a way that the sigma components of the rotation rate signal which are characteristic of a slow rollover process unfiltered this further. Pass through the low-pass filter and then only compare it with a fixed trigger threshold when the integrated rotation rate signal reaches a fixed angle threshold. Since this integrated rotation rate signal corresponds approximately to the inclination angle of the vehicle, this angular threshold value represents a minimum inclination angle. Only when this minimum inclination angle is reached is the filtered rotation rate signal compared with the fixed threshold value, which preferably represents a minimum rotation rate. Thus triggering a safety device is also for slow overs - at the latest when the 'vehicle is on its side - secured.
- a third low-pass filtering can be of the rotation rate signal are performed, wherein the cutoff frequency of the low pass filter used between the value of the cutoff frequency of the first low-pass filter and the value of the 'cut-off frequency of the second low-pass filter is located.
- the sensor signals of the other sensors indicating the stability of the vehicle can be used for plausibility checking, so that tripping is only possible if all sensor signals actually indicate an impending rollover.
- the vertical acceleration of the vehicle can be used for plausibility checking by setting the trigger threshold such that triggering only takes place if the vertical acceleration deviates significantly from the value 1g.
- roll-over operations of the screw ramp type or rollovers over a cliff are detected, in which the vertical acceleration indicates weightlessness.
- Figure 1 A block diagram for performing the method according to the invention
- Figure 2 a rollover characteristic curve in the representation of a - ⁇ x -J ⁇ x dt-
- FIG. 3 a further rollover characteristic curve to explain the functioning of the arrangement according to FIG. 1
- FIG. 4 a block diagram as a further exemplary embodiment
- FIG. 1 shows a security system with an arrangement for carrying out the method according to the invention.
- This arrangement initially consists of a rotation rate or gyro sensor B ⁇ , which generates a rotation rate signal proportional to the angular velocity ⁇ x (rotation rate) about the longitudinal axis (x-axis) of a vehicle, the three low-pass filters TP ⁇ 1 , TP ffl and TP and for the purpose of integration of the rotation rate signal ⁇ x is fed to an integrator Int.
- an offset and offset drift correction is carried out by using the low-pass filter TP filtered rotation rate signals are subtracted from the output signals of the low-pass filters TP ⁇ ⁇ and TP ⁇ 2 by means of adders A1 and A2.
- the 'used for the offset and the offset drift correction low-pass filter TP is from 1 order with a cut-off frequency ⁇ f from about 10mHz.
- comparators K ⁇ ⁇ and K ⁇ 2 are supplied with the respective low-pass filtered and offset-corrected rotation rate signal via their non-inverting inputs, while at their inverting inputs
- a threshold value generation circuit SWn or SW ⁇ 2 is connected. To generate a corresponding trigger threshold, these threshold value generating circuits SWn and SW ⁇ 2 are supplied with the integrated yaw rate signal J ⁇ x dt generated by the integrator Int.
- the cut-off frequency f ⁇ * ⁇ of the low-pass filter TP ⁇ * ⁇ is selected so that the signal components of the rotation rate signal ⁇ x which are characteristic of a rapid rollover pass this low-pass filter unfiltered; the districtnord- "voltage cut-off frequency of this lies in some Hz. -
- the integral value J ⁇ x dt generated by the integrator Int is used by the threshold value generation circuit SW ⁇ to generate a trigger threshold value S ⁇ ⁇ which is present at the inverting input of the comparator K ⁇ .
- a vehicle-specific rollover characteristic curve is used to determine this trigger threshold value S ⁇ ⁇ as a function of the integral value J ⁇ x dt, as is shown by way of example with an ⁇ x -J ⁇ x dt diagram according to FIG. 2.
- ⁇ x represents the amount of the rotation rate, i.e.
- the ⁇ x ⁇ * J ⁇ x dt graph of this diagram which, contrary to the straight line shown in FIG. 2, can be implemented, for example, as a multi-stage staircase function, divides the ( ⁇ x ,
- the ( ⁇ gre ⁇ z , 0) combination or (0, ⁇ i ⁇ P ) combination represents a limit state of a vehicle with a rotation rate ⁇ g r e nz in the x direction and an inclination angle of 0 ° or with a rotation rate 0 and one Tilt angle (static tilt angle) ⁇ i P that leads to a rollover.
- These parameters are vehicle-specific and must therefore be determined separately for each vehicle type.
- the associated ⁇ x value is determined by means of the (D x -J ⁇ x dt graph according to FIG. 2), which is the trigger threshold value S ⁇ * j is fed to the comparator K ⁇ * ⁇ If the value generated by the low-pass filter TP ffi exceeds this trigger threshold value S ⁇ * ⁇ , a trigger signal is output to a safety device via an OR gate G-.
- the Schwellwerter Wegungsscnies from the SW * ⁇ 2 to the comparator "K ⁇ 2 output trigger threshold value S ⁇ 2 other hand, is defined as a fixed value and is determined by the x ⁇ x dt -J ⁇ -diagram shown in FIG 3. Thereafter, should a trip after reaching a minimum rotational rate ( ü mm - of the vehicle only take place if a certain J ⁇ x dt value is generated, i.e. the vehicle has a certain minimum inclination angle cc ge n z .
- the minimum rotation rate ⁇ m , n depends on the frequency content of the rotation rate signal and thus on the limit frequency the use low pass filter TP ⁇ 2 .
- the limit value is set in such a way that the safety device is triggered in the event of slow rollovers at the latest when the vehicle is on its side, but does not trigger when entering a steep wall, which as a rule does not have a 90 ° angle.
- the lateral acceleration of the vehicle detecting sensor B ay whose Bestructungssignal- a first y a low-pass filter TP y is supplied to the cutoff frequency f y in such a manner is set to the a lateral acceleration to supply characteristic signal components unfiltered for the purpose of comparison with a threshold value S y to the non-inverting input of a comparator K y , the output of this comparator K y being connected to the threshold value generating circuit SWn ' .
- the threshold value S y is output by a threshold value generation circuit SW 2 ⁇ to the inverting input of the comparator K y and corresponds to a certain amount of lateral acceleration.
- this ' threshold value S y is exceeded by the filtered acceleration signal, the level change thereby triggered has the effect that the rollover characteristic curve according to FIG. 2 used to output the trigger threshold value S ⁇ * ⁇ is shifted towards smaller values. This makes the arrangement more sensitive to high cross-acceleration of the vehicle and it ensures a shorter reaction time from the time when an impending rollover is detected until the safety device is triggered.
- the threshold value generating circuit SWn is also caused to output trigger threshold values S ⁇ * ⁇ shifted to smaller values.
- the acceleration sensor B y for the detection of the transverse acceleration a y and the acceleration sensor B z for the detection of the vertical acceleration can of course be used at the same time in order to ensure an optimal dynamic adaptation of the triggering threshold S ⁇ ⁇ ,
- the outputs of the two comparators K y and K z are separately connected to the threshold value generating circuit SWn via a separate line (shown in FIG. 1 by two lines shown in broken lines in parallel).
- FIG 4 initially differs from that of Figure 1 by the number of ⁇ for the evaluation of the output from the angular rate sensor angular rate ⁇ B x provided low-pass filter and the corresponding downstream comparators associated with increasing Schwellwerter Wegungsscrien.
- the Low-pass filter TP ⁇ 2 corresponds in terms of its function and design to the low-pass filter TP ⁇ 2 from FIG. 1, that is to say is provided for detecting slow flashovers.
- Each of the three low-pass filter TP ⁇ , TP ⁇ 2 and TP ⁇ 3 is in each case a comparator K ⁇ ⁇ , K m2 and K ⁇ 3 ⁇ with associated Schwellwerter Wegungsscariaen SWn, SW 12 and SW * downstream 3, wherein each of these Schwellwerter Wegungsscrienen ⁇ a trigger threshold value S ⁇ , S ⁇ 2 and ⁇ 3 S output.
- the outputs of the three comparators K ⁇ ⁇ , K ⁇ 2 and K ffl3 are also routed to an OR gate Gi, which in turn controls an AND gate G 2 and an AND gate G 3 , each with two inputs.
- the signals output and TP ⁇ 3 are also subjected to an offset and offset drift correction, as shown in FIG. 1, by subtracting the signal output by the low-pass filter TP by means of adders A * ⁇ to A 3 .
- 2 "output trigger threshold value S ⁇ 2 or the Schwellwerter Wegungssciens SW 12 is set as the low-pass filter TP ffi2 according to FIG. 1, the cutoff frequency f ⁇ 3 of the additional low-pass filter TP ⁇ 3 will now be adjusted so that the value of f between the value of the cutoff frequency ⁇ ⁇ of first low-pass filter TP ⁇ * ⁇ and the value of the cutoff frequency f ⁇ 3 of the second low-pass filter TP ⁇ 2 is located.
- the adjusted by the Schwellwertermaschineungssciens SW ⁇ 3 relevant threshold values ⁇ gre z and comin (threshold value as a trigger S ⁇ 3) also somewhat deeper than in the Arrangement used according to Figure 1.
- the cut-off frequencies f y ⁇ and f y2 of the low-pass filter TP y ⁇ and TP y2 are set so that the first low-pass filter TP y - ⁇ a high cut-off frequency f y ⁇ and the second low-pass filter TP y2 a low cut-off frequency ⁇ . having.
- the outputs of the comparators K y ⁇ and K y2 are additionally routed via an OR gate G to the second input of the AND gate G 2 , so that triggering is only permitted if the transverse acceleration has a minimum value I y I by appropriately setting the threshold values S y ⁇ and S y2 , as a result of which rollover processes in the sand bed or rollover processes caused by a curb impact are detected .
- a triggering via a further OR gate G thus only takes place if the OR gate G 1 passes on a trigger signal and at least one of the comparators K y * ⁇ or K y2 generates a high level.
- the evaluated acceleration signals of the acceleration sensor B az also serve to make the plausibility of the rotation rate signals ⁇ x possibly triggering, in that the outputs of the comparators K z1 and K z2 are routed via an OR gate G 6 to one input of the AND gate G 3 and whose second input is connected to the output of the OR gate Gj.
- the cut-off frequencies f z1 and f_- are the low-pass filters TP z * ⁇ and TP z2 and the threshold values S z ⁇ and S * ⁇ to be provided by the threshold value generation circuits SW 3 ⁇ and SW 32 so that triggering is only permitted if the acceleration in the vertical direction deviates significantly from the value 1g ⁇ gravitational acceleration), which means in particular roll-over operations of the screw ramp type (a z greater than 1g), in which a release is to take place in the upward movement or a rollover over a cliff, in which the a z value approximately indicates weightlessness.
- the cut-off frequencies fzi and fz2 of the low-pass filter TP z * ⁇ and TPz 2 are also set such that the first low-pass filter TP z1 has a high cut-off frequency f z * ⁇ and the second low-pass filter TP z2 has a low cut-off frequency fz 2 .
- the evaluated acceleration signals a z of the acceleration sensor B az - as can also be implemented in the arrangement according to FIG. 1 - can be used for dynamic adaptation of the triggering threshold values S ⁇ ⁇ by the outputs of the comparators K z * ⁇ and K z ⁇ via separate lines to separate inputs of the threshold value generation circuit SW ffi ⁇ , as shown in Figure 4 with dashed connecting lines V.
- the trigger threshold value S ⁇ ⁇ is thus set as a function of the output values of the comparators K y * ⁇ , K y 2, K ⁇ and K z2 .
- the number of low-pass filters used for evaluating the acceleration signals need not be limited to two. If, for example, a third low-pass filter is used for evaluating the acceleration signals a y and a z , their cut-off frequencies are set in such a way that the first low-pass filter has the highest cut-off frequency and the third low-pass filter has the lowest cut-off frequency. Corresponding rules apply to the threshold values.
